Turning the tide on big cat trade: Expert opinion on trends and conservation lessons from the Republic of Korea.

Unsustainable trade in big cats affects all species in the genus, Panthera, and is one of the foremost threats to their conservation. To provide further insight into the impact of policy interventions intended to address this issue, we examine the case study of the Republic of Korea (South Korea), which in the early 1990s was one of the world's largest importers of tiger (Panthera tigris) bone and a major manufacturer of tiger-derived medicinal products. In 1993, South Korea became a Party to the Convention on International Trade in Endangered Species (CITES) and introduced a ban on commercial trade in CITES Appendix I-listed big cats a year later. We used an expert-based questionnaire survey and an exploration of the CITES trade database to investigate what has since happened to big cat trade in South Korea. Expert opinion suggested that big cat trade has likely substantially reduced since the early 1990s, as a result of the trade ban and broad socioeconomic changes. However, illegal trade has not been eradicated entirely and we were able to confirm that products reportedly derived from big cats were still publicly available for sale on a range of Korean online marketplaces, sometimes openly. The items most commonly reported by respondents from post-1994 trade and supported by expert-led evidence were tiger and leopard (Panthera pardus) skins and tiger bone wine. Although South Korea may provide a useful case study of a historically significant consumer country for tiger which has made strong progress in addressing unsustainable levels of big cat trade within a short period of time, there remains a need to address recalcitrant small-scale, illegal trade. We also recommend further investigation regarding reports of South Korean nationals being involved in illegal trade in tiger-derived products in Southeast Asia.

Active afforestation of drained peatlands is not a viable option under the EU Nature Restoration Law.

The EU Nature Restoration Law (NRL) is critical for the restoration of degraded ecosystems and active afforestation of degraded peatlands has been suggested as a restoration measure under the NRL. Here, we discuss the current state of scientific evidence on the climate mitigation effects of peatlands under forestry. Afforestation of drained peatlands without restoring their hydrology does not fully restore ecosystem functions. Evidence on long-term climate benefits is lacking and it is unclear whether CO2 sequestration of forest on drained peatland can offset the carbon loss from the peat over the long-term. While afforestation may offer short-term gains in certain cases, it compromises the sustainability of peatland carbon storage. Thus, active afforestation of drained peatlands is not a viable option for climate mitigation under the EU Nature Restoration Law and might even impede future rewetting/restoration efforts. Instead, restoring hydrological conditions through rewetting is crucial for effective peatland restoration.

FSC-certified forest management benefits large mammals compared to non-FSC.

More than a quarter of the world's tropical forests are exploited for timber1. Logging impacts biodiversity in these ecosystems, primarily through the creation of forest roads that facilitate hunting for wildlife over extensive areas. Forest management certification schemes such as the Forest Stewardship Council (FSC) are expected to mitigate impacts on biodiversity, but so far very little is known about the effectiveness of FSC certification because of research design challenges, predominantly limited sample sizes2,3. Here we provide this evidence by using 1.3 million camera-trap photos of 55 mammal species in 14 logging concessions in western equatorial Africa. We observed higher mammal encounter rates in FSC-certified than in non-FSC logging concessions. The effect was most pronounced for species weighing more than 10 kg and for species of high conservation priority such as the critically endangered forest elephant and western lowland gorilla. Across the whole mammal community, non-FSC concessions contained proportionally more rodents and other small species than did FSC-certified concessions. The first priority for species protection should be to maintain unlogged forests with effective law enforcement, but for logged forests our findings provide convincing data that FSC-certified forest management is less damaging to the mammal community than is non-FSC forest management. This study provides strong evidence that FSC-certified forest management or equivalently stringent requirements and controlling mechanisms should become the norm for timber extraction to avoid half-empty forests dominated by rodents and other small species.

Agri-environmental policies from 1960 to 2022.

For both research and practice, it is paramount to understand what, where and when agri-environmental policies have been put in place. Here we present a database of 6,124 agri-environmental policies implemented between 1960 and 2022 in about 200 countries. The database comprises a wide range of policy types (including regulations and payment schemes) and goals (such as biodiversity conservation, safer pesticide use and reducing nutrient pollution). We illustrate the application of the database by exploring the association between economic development and agri-environmental policies and between the soil-related, agri-environmental policies of countries and their border discontinuities in cropland erosion. A strong, positive link between economic development and implemented agri-environmental policies is revealed, and it is found that 43% of all global border discontinuities in soil erosion between countries can be explained by differences in their policies.

Landscape-scale benefits of protected areas for tropical biodiversity.

The United Nations recently agreed to major expansions of global protected areas (PAs) to slow biodiversity declines1. However, although reserves often reduce habitat loss, their efficacy at preserving animal diversity and their influence on biodiversity in surrounding unprotected areas remain unclear2-5. Unregulated hunting can empty PAs of large animals6, illegal tree felling can degrade habitat quality7, and parks can simply displace disturbances such as logging and hunting to unprotected areas of the landscape8 (a phenomenon called leakage). Alternatively, well-functioning PAs could enhance animal diversity within reserves as well as in nearby unprotected sites9 (an effect called spillover). Here we test whether PAs across mega-diverse Southeast Asia contribute to vertebrate conservation inside and outside their boundaries. Reserves increased all facets of bird diversity. Large reserves were also associated with substantially enhanced mammal diversity in the adjacent unprotected landscape. Rather than PAs generating leakage that deteriorated ecological conditions elsewhere, our results are consistent with PAs inducing spillover that benefits biodiversity in surrounding areas. These findings support the United Nations goal of achieving 30% PA coverage by 2030 by demonstrating that PAs are associated with higher vertebrate diversity both inside their boundaries and in the broader landscape.

The impact of green taxes on green innovation of enterprises: a quasi-natural experiment based on the levy of environmental protection taxes.

Green innovation is a strategic choice for Chinese enterprises to achieve in balancing economic performance and environmental benefits. Environmental protection tax (EPT) is the first green tax in China. How to fully leverage the institutional dividends of environmental tax reform to achieve green innovation in enterprises is of great significance for the high-quality development of China's current economy. This study takes the levy of environmental protection taxes as the quasi-natural experiment and uses DID, DDD, PSM-DID and so on to verify the impact of EPT on green innovation. The results show that EPT can improve green innovation through the path of legitimacy pressure and legitimacy management. Notably, the effects are more obvious in enterprises with non-state-owned, low-financing constraints and located in the eastern region. Furthermore, green innovations under the push of environmental protection tax can improve long-term performance, while it has a negative effect on short-term performance. The levy of EPT has the dual dividend effect of economy and environment. Moreover, this study explores the source of the legitimacy pressure and the strategic response of enterprises and provides guidance for government's precise implementation of policies to optimize the role of EPT in green innovation.

Science and the legal rights of nature.

We review the use of science by lawmakers and courts in implementing or rejecting legal rights for nature in Ecuador, India, the United States, and other jurisdictions where some type of rights of nature have been recognized in the legal system. We then use the "right to evolve" to exemplify how interdisciplinary work can (i) help courts effectively define what this right might entail; (ii) inform how it might be applied in different circumstances; and (iii) provide a template for how scientists and legal scholars can generate the interdisciplinary scholarship necessary to understand and implement the growing body of rights-of-nature laws, and environmental law more generally. We conclude by pointing to what further research is needed to understand and effectively implement the growing body of rights-of-nature laws.

Understanding the nexus between environmental, social, and governance (ESG) and financial performance: evidence from Chinese-listed companies.

Before discussing how to balance and decide on environmental, social, and corporate governance (ESG) and traditional revenue enhancement projects, it is crucial to clarify the relationship between corporate financial performance (CFP) and ESG. However, little attention has been paid to the nexus of ESG and CFP. This paper attempts firstly to investigate the bidirectional causality of ESG and CFP, followed by the micro-foundations, and finally, the moderating effect of intrinsic factors. A GMM-PVAR method was used to examine the research hypotheses, which can effectively deal with endogenous problems that have been ignored by traditional literature. The findings of this research demonstrate that CFP promoted ESG growth, but ESG did not boost CFP. This asymmetric causality was because CFP had a supportive effect on the environment and society pillars, while the social pillar cannot promote CFP, and the environment pillar negatively affects CFP. The relationship between ESG and CFP was moderated by total quality management, environmental sensitivity, and the pay gap. Furtherly, a panel threshold model was constructed to access the threshold effects of ESG on CFP, showing an inverted U-shape. Based on these findings, the theoretical implications, managerial prescriptions, and limitations are also discussed.
